It would be useful if points earned had an expiration date that could be administered site-wide or by rule - e.g., if you earned 10 points for submitting a link, those points might only be valid for a period of "n" days, "n" being an admin choice. In this way, site owners could further motivate users to earn and spend points on the site. I see that one can edit individual points and expire them, but I don't see that there is a site-wide admin function for same...
Thank you in advance for considering this feature request.
